Microchip Technology, Inc. Laser Drivers SY88702KI

The SY88702KI is a high-speed laser diode driver designed for optical transmission applications, capable of operating at data rates up to 622 Mbps. It features a single 5V power supply and supports modulation currents up to 25mA. The device includes differential PECL inputs and complementary open collector outputs, with a maximum output current of 25mA. The modulation current is set by an external resistor, RSET, connected to a voltage reference pin. The SY88702KI is housed in a compact 10-pin MSOP package, making it suitable for space-constrained designs. It operates over an ambient temperature range of -40¬8C to +85¬8C, making it suitable for industrial applications. The device is ideal for use in SONET applications and requires careful consideration of external resistors to manage power dissipation and laser diode matching.
